Hrmmm, this patch has no effect. Digging into aclocal, it seems that
AC_CONFIG_MACRO_DIR isn't actually an existant macro, and is internally
aliased to AC_CONFIG_MACRO_DIRS (plural). I guess this is why your
ifndef is a no-op. Mocking out AC_CONFIG_MACRO_DIRS and calling that
in configure.ac works for me. See attached.
